| + | ==== Centos 6 to 7 Upgrade ==== | ||
| + | |||
| + | I've followed [[https://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool]] without issue.\\ | ||
| + | But after reboot i've started seeing following error "libpcre.so.0" not found. | ||
| + | |||
| + | After looking further it appeared to the issue with "grep" package. | ||
| + | After Successful reboot simply downgrade the grep package and error will disappear. | ||
| + | |||
| + | Also it is good idea to place selinux in permissive mode before you start upgrade. | ||

| + | best bet is to contact vmware, but temporary fix should be as follow | ||
| + | <code bash> | ||
| + | try booting with pci=nocrs kernel command line option. | ||
| + | This parameter is used to discard ACPI resource information for various devices. | ||
